| Abstract | Food packaging characteristics are highly important since their function is not only topackage food but also to protect food from external materials such as oxygen and preventmechanical disturbance, thus maintaining the food quality. Smart packaging, which also plays arole as active packaging, has the capability of inhibiting the growth of microorganisms, leadingto a longer shelf-life of food. In this research, TiO2/chitosan nanocomposite-based packagingwas used since both TiO2 and chitosan were proven as antimicrobial substances. Synthesis of thenanocomposite was conducted with the aid of ultrasonic energy to achieve higher efficiency. Theresults showed that the mechanical properties such as percentage of elongation, tensile strength,and young modulus of TiO2/chitosan nanocomposite films meet the JIS standard. These filmsalso have higher antimicrobial activity toward Bacillus and Escherichia coli compared to theamoxicillin standard. The thermal properties of the packaging films revealed that these films havesufficient thermal stability for application in the moderate range of temperatures. In addition,these films do not require high temperatures to decompose therefore they can decomposenaturally in the environment as indicated by the results of biodegradability tests, which showa packaging degradation capacity of 7.43 x 10-4 g/day. The composition of the nanocompositeTiO2/chitosan greatly affects the mechanical and antibacterial properties of the films. |
